CINEMATOGRAPH.

Specification of Letters Patent.

Patented J an. 2, 1917.

Original application filed April 10, 1914, Serial No 831,015. Divided and this aonlication filed Kay 8, 1916. Serial No. 95,039.

T 0 all whom it may concern:

Be it known that I, Laxonox McConiucn, a citizen of the United States, resid ing at Port Huron, in the county of St. Clair and State of Michigan, have invented certain new and useful Improvements in Cinematographs, of which the following is a specification.

This invention relates to improvements in cinem-atographs.

The present application is a division of my copending application for patent, Serial No. 831,015, filed April 10, 1914, the construction and arrangement of parts in the. present case being directed to the means controlled by the cinematograph for light ing a lamp or lamps in rear. of a translucent screen to show actual light thereon where representation of light appears in a picture.

The prime object of my invention is to provide a plurality of lamps, a cinematograph, and means controlled by the cinematograph for lighting a lamp or lamps synchronously with the production of a picture on the screen.

The invention also comprehends improvements in the details of construction and arrangement of parts which will be hereinafter described and particularly pointed out in the claims.

In the drawing: Figure 1 represents diagrammatically an elevation of the invention. Fig. 2 is a. diagrammatic View illustrating more particularly the Wiring.

The numeral 1 indicates a moving picture machine, and 1, the film feeding wheel thereof. On the shaft of the wheel 1, is a contact roll having spaced contacts 2, 3, 4, 5 and 6, separated by insulation 7 8 indicates conventionally a film, which passes over the wheel 1 in the usual manner.

9 represents a drum containing a tape 10, formed with suitable perforations 11, the tape passing over the contact roll, and is wound on a receiving drum 12.

Located some distance in front of the moving picture machine is a translucent screen 13, and in rear of the same is a lamp casing 1A containing a plurality of.fixed lamps 15.

Cooperating with the contacts 2 to 6, and the perforations 11 in the tape, are fingers 16, and to each finger is connected a wire 17. These wires lead directly to the respective lamps in the lamp casing, as shown in the drawing. Arranged to be in constant engagement with contacts 2 to 6, are fingers 18, all connected to a wire 19. The Wire 19 leads to a source of electricity, indicated in the present instance by a battery 20, and to the latter is connected a wire 21. Extending from the wire 21 are branch wires 22, each leading to a lamp 15, to complete a circuit to light the lamps in the operation of the apparatus. As the film 8 passes over the wheel 1 the latter is rotated, hence the contact roll is rotated, and as the tape 10 is held against the periphery of this roll, the tape moves synchronously with the film. The perforations in the tape are arranged with reference to the pictures on the film, so that when a picture is thrown on the screen. representing a light, a finger or fingers will make contact with a contact or contacts 2 to 6, and a lamp or lamps behind the screen will be lighted. The result is the light showing through the screen will appear at the point in the picture where the representation of light is shown. Hence actual light appears in the picture and renders reproduction more realistic.

The perforations in the tape may be variously arranged to produce the desired effect, and obviously one or more of the lamps may be lighted, depending entirely upon the character of the picture on the screen, and the lighting effect desired.

What I claim is 1. In combination, cinematograph mechanism, a translucent screen on one surface of which pictures are'exhibited, a lamp positioned in rear of the screen, and means operated by cinematograph mechanism for lighting the lamp.

2. In combination, cinematograph mechanism, a translucent screen on one surface of which pictures areexhibited, a lamp positioned in rear of the screen, and means operated synchronously with and by cinematograph mechanism for lighting the lamp.

3. In combination, cinematograph mechanism, a translucent screen on one surface of which the picturesare exhibited, a plurality of lamps in rear of the screen, and means operated by and with cinematograph mechanism to light certain of the lamps to show in. the reproduced. picture actual light at a particular point.

4. In combination, cinematognaph mechanism, a translucent screen on one surface of which the pictures are exhibited, a lamp positioned to show actual light on the screen at a point where the representation of light appears in the picture shown on the screen, and means operated by the cinematograph mechanism for lighting the lamp.

5. In combination, cinematograph mechanism, a translucent screen on one surface of which the pictures are exhibited, a plurality of lampspositioned behind the screen, and means including a perforated tape operated synchronously with the cinematograph mechanism for lighting a lamp or lamps to show actual light on the screen at points where the representation of light appears in the picture on said screen.

6. In combination, cinematograph mechanism, a translucent screen on one surface of which the pictures are exhibited, a plurality of lamps positioned in rear of the screen, and means controlled by the cinematograph mechanism to light a particular lamp to cor-v respond with the picture produced on the screen to show actual light where the representation of light appears in the picture.

7. In combination, cinematograph mechanism including a shaft, a translucent screen on one surface of which the pictures are exhibited, a plurality of lamps positioned in rear'of the screen, a series of contacts carried by the shaft, a wire connected with the contacts and to the lamps, a perforated tape operating on the contact roll, a series of fingers cooperating with the tape and the contacts on the roll, and wires leading from the respective fingers to the respective lamps, whereby when contact is made through the perforations the lamps will be lighted and show actual light pn the pictures on the screen at points where the representation of light appears.

8. In combination, cinematograph mechanism, a translucent screen on which the pictures are exhibited, a plurality of lamps in rear of the screen, a rotative contact element, a perforated tape operating with the rotative contact, a wire leading from the contacts on the rotative element to the lamps, a plurality of fingers cooperating with the perforations in the tape and the contacts, and wires extending from the fingers to the lamps whereby when a finger engages one of the contacts through a perforation a lamp will be lighted to show through the screen and t0 the picture appearing thereon.

9. In combination, cinematograph mechanism, a translucent screen, a plurality of lamps in rear of the screen, and electric means synchronously operated by the cinematograph mechanism for lighting the lamps to show actual light where the representation of light appears in the picture on the screen.

10. In combination, cinematograph mechanism, a translucent screen, a plurality of lamps in rear of the screen, and means operated by the cinematograph for controlling the lamps.

11. In combination, cinematograph mechanism including a film, a translucent screen, a plurality of lamps in rear of the screen, and means operated synchronously with the film to control the lamps to show actual light in the picture produced on the screen from the film.

In testimony whereof I affix my signature in the presence of two witnesses.
